Review on ☕ Coffee On-the-Go: Stojo Collapsible Travel Cup with Straw - Perfect Food Service Equipment and Supplies for Travelers by Franciszka Majewska ᠌

The official instructions have advice: before use, wash the glass and soak in warm water with a spoonful of vinegar for 12 hours. After that, my taste disappeared. I've been using it for about two months. Excellent silicone, beautiful color, convenient to take with you and take care of the environment. I dreamed about this glass and did not regret at all
